Aerothermal Engineer

Whisper Aero • Nashville, TN

44d • Onsite

About The Position

Whisper Aero is seeking a diligent, detail-oriented and hardworking Aero-thermal Engineer familiar with different fidelity heat transfer codes (from network models to conjugate heat transfer CFD codes) to assist with the design of thermal analysis in advanced electric propulsion systems to work onsite in Nashville, TN. This role will be focused on developing cooling schemes and carrying out detailed thermal analysis for integrated motor/propulsor problems. It will involve some working knowledge of heat sources in electric motors and power electronics associated with electric propulsors. They will drive key thermodynamic, aero performance, and aero-thermo-structural design decisions and regularly work closely with our Flight Sciences Lead, Flight Sciences team, Chief Engineer, and Technical Project Leads. In this role, you will work with the team to identify thermal constraints for future propulsors, manage cooling schemes for propulsors in different thrust classes, develop thermal codes, provide pre-test predictions, and code validation.
